Document Summary
Focus = originating point of the eq, subearth"s surface epicentre = areas at the surface above the focusing moment magnitude scale, one increment = ten sheepcote increase in waves. Normaltension > stretching > cutting > normal fault reversecompression > shortening > folding > reverse strike slip (san andrea geological fault )shear > shearing > bending > bang slick. Shield bigger, hawaii, thin lava , effusive composite , gases build up, explosive eruptions, conic , steep. Subduction zones, hotspots, ocean oor dissemination ; intrusive (magma) and extrusive (lava ) Orogenesis = mountain edi ce - continental and oceanic (coastal hatful - andes mountain) - oceanic and oceanic (underwater volcanos) - continental and continental (inland mountains - himalayan.
